SAND-LOADING DEVICE.

Patented July 13, 1920.

Application filed October 1, 1919. Serial No. 327,621.

To aZZ whom it may concern.-

Be it known that I, GEORGE MIOHNA a citizen of Czechoslovakia, residing at Albany, in the county of Albanyand State of New York, have invented certain new and useful Improvements in Sand-Loading Devices, of which the following is a specification.

The primary object of the present invention resides in a sand loading device wherein there is employed a rotatable frame carrying scoop buckets upon the ends thereof adapted for transferring sand or similar material from one point such as a bank to a receiving chute for delivery into a ve hicle.

A further object of the invention is to provide a sand loading device wherein there is employed a pair of scoop buckets or shovels adapted in their path of movement to transfer material from a pile to an inclined runway with means associated with the runway and in the path of movement of the shovels to insure the delivery of the material into the runway.

With the above general objects in view and others that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts herein fully described and shown in the accompanying drawings wherein like reference characters indicate similar parts throughout the several views.

In the drawings,

Figure 1 is a longitudinal sectional view of a sand loading device constructed in accordance with the present invention and illustrating one of the shovels engaging the resiliently mounted side board of the chute,

Fig. 2 is a top plan view thereof,

Fig. 3 is a side elevational view, similar to Fig. l with one of the scoops illustrated as having passed the resiliently mounted side board of the chute,

Fig. at is a cross sectional view taken on line lVlV of Fig. 3, and

Fig. 5 is a fragmentary perspective view of the resiliently mounted side board of the chute with a portion of the adjacent frame.

Briefly described, the present invention aims to provide a sand loading device in the form of a rack or frame that may be positioned adjacent a sand bank or pile of material that is adapted to be transferred from one point to another and particularly includes a pair of shovels moving in a circular path by manually operable means for gathering and delivering sand or other material. A chute is carried by the frame and is adapted to receive the material from the shovels while the resiliently mounted side board is carried by the chute adapted to be engaged by the forward edge of the shovel to insure the delivery into the chute of the entire contents of the shovel, the board swinging on a pivot against the tension of its resilient means by the forward movement of the shovel to permit a clearance thereof after which the board is returned to'its initial position for engagement with the next approaching shovel.

Referring more in detail to the accompanying drawings, there is illustrated a frame embodying end standards 5 and 6 connected by longitudinal spaced braces 7, the standards 6 being slightly elevated above the bars 7 and having journaled in the upper ends thereof, the horizontal shaft 8 retained in position by the strap bearings 9 and being rotatable by the crank handle 10.

The scoop structure will first be described and includes radial arms 11 projecting from the shaft 8 and having secured to opposite faces of the outer ends thereof scoops or shovels 12 having retaining means 13 passing through the bottom wall thereofand through the arms 11. Each shovel 01' scoop 12 includes a relatively short front wall 22 and a relatively long rear or bottom wall 14:, the same being connected by inclined side walls 15 as clearly illustrated in Figs. 1 and 3.

The opposite end of the frame from the shaft 8 is provided with a receiving chute suitably supported upon the end standards and the cross bars 7 and including an inclined bottom wall 16 extending from one side of the frame to a point beyond the other side thereof as indicated in Figs. 2 and l with one side wall 17 cut away to provide a clearance for the upper cross brace 7. The opposite side wall 18 of the chute extends upon a horizontal line inwardly of the side frames 7 while the portion 18 outwardly of the frame is declined as illustrated in Fig. 4%. The upper edge of the side wall 18 of the chute has pivoted thereto as at 19 a side board 20 that is resiliently maintained in a substantially vertical position as indicated in Figs. 1 and 3 by the coil springs 21 extending from the frame'to the side boards 20 for resiliently maintaining the same in the position shown.

In the operation of the device, the shovels 12 are adapted for conveying material from one point to the chute 16, the lower front Wall 13 gathering the material in the scoop when the shaftS is rotated by the crank 1O and during the circular movement of the scoops, the material therein finally rests upon the bottom wall 1 1 when the scoops are. in position to be delivered to the chutes 16. As illustrated in Fig. 1, the finger let upon the forward edge of the bottom wall 14 engagesthe upper edge of the resiliently mounted side board 20 to insure all of the material in the scoop being delivered into the chute and by continued movement of the scoop, the sideboard is adapted to swing in a circularpath of movement as indicated by -dotted linesin Fig. 1 whereupon the scoop engagingthe same is freed therefrom, and the side board permitted to return to its normal upright position and be ready for contact by the succeedingscoop. lVith the movement of adevice ofthis character, sand or other material to be loaded from a bank for pile into a Vehicle by means of first shoveling tlie material' into the scoops described herein, it will be obvious that allof thematerial will be safely conducted to the chute 16 by the scoops engaging the side boards 20 for positively delivering the entire contents thereof into the chutes.

' l/Vhile there is'herein shown and described what is believed to be the preferred embodiment of the invention, it is nevertheless to r be understood that minor. changes may be made. in the form combination and arran ement of parts without departing from the spirit and scope of the inventionas claimed.

' said shaft} What is claimed as new is 1. A sand loading device comprising a frame, a shaft journaled therein, arms ra dially extending from said shaft, scoops secured to the outer ends of said arms, a chute supported by said frame, a. resiliently mounted side board carried by said chute positioned in the swinging path of movement of said scoops and means for operating 2. A sand loading device comprising, a frame, a chute supported thereby, a resiliently mounted sideboard carried by said chute and means for delivering sand to said chute adapted. to engage said side board frame, a chute supported thereby, a resili-- ently mounted side board carried by said chute, means for delivering sand to said chute adapted to engage said side board during the movement thereof, said means including a plurality of. scoops, each having a relatively short and long rear wall respectively, and fingers carried by the for-- ward edges of the rear; walls and means for moving the scoopsin a circular path with the fingers thereof in position to engage the resiliently mounted side boards of the chute.

In testimony whereof I afiix my signature.
